Description

Anastasia Lyskovich and co-authors test how scandium and zirconium additions change a heat-conducting aluminum alloy, published in 2025. Alloys of aluminum with zinc and calcium conduct heat well, cast easily, and resist corrosion, suiting them to electronics and electric vehicles, but they lack strength. Adding small amounts of other metals is a standard way to harden them.

Swapping some scandium for zirconium barely changed the phase makeup, though the two metals spread differently through the grains, and grain size shrank. A heat treatment raised hardness in all variants through tiny hardening particles. The swap lowered heat conduction and top strength, but improved stretch before breaking. All aged variants resisted corrosion well in salt solution, with the zirconium ones corroding more slowly and resisting pitting better.
